Objective:To evaluate the item properties and applicability of the eHealth Literacy Scale in Web 3.0 context (eHLS-Web 3.0) among diabetic patients by applying classical test theory (CTT) and item response theory (IRT) to provide a new effective tool for assessing the level of eHealth literacy among diabetic patients.Methods:A cross-sectional study design was adopted and 230 diabetic patients from the inpatient endocrinology department of the Affiliated Yantai Yuhuangding Hospital of Qingdao University were selected by convenience sampling from November 2022 to May 2023 and were surveyed by using the self-general information questionnaire and eHLS-Web 3.0. The correlation coefficient method, Cronbach α coefficient, Guttman split-half reliability coefficient, and structural validity in CCT were used, and discriminant validity, convergent validity, and Samejima Graded Response model in IRT were used to evaluate the scale items. Results:The CTT results showed that Cronbach α coefficient for the eHLS-Web 3.0 was 0.973, the Guttman split-half reliability coefficient was 0.894, and the correlation coefficient between the items and the total score of the scale ranged from 0.708 to 0.845 (all P<0.01). Exploratory factor analysis extracted three common factors with a cumulative variance contribution rate of 76.75%, and the confirmatory factor analysis model had a good fit. The reliability of each dimension combination was >0.60, and the average variance extracted was >0.50. The square root of the average variance extracted from each dimension (0.817, 0.875, 0.845) was greater than the correlation coefficient between this dimension and other dimensions (0.742, 0.763, 0.715). The IRT results showed that the discrimination parameter of all the items ranged from 2.174 to 4.054, the difficulty coefficients increased with the increase of the level (- 2.471 - 2.187), and the average information content of all the items ranged from 1.217 to 2.609. Conclusions:The eHLS-Web 3.0 has good characteristics among diabetic patients as tested by CTT and IRT, and can be used as an effective tool to assess the eHealth literacy level of diabetic patients in China.

Objective:To explore the influencing factors and pathways of home-based exercise rehabilitation compliance in patients after percutaneous coronary intervention (PCI), so as to provide theoretical basis for formulating targeted intervention program.Methods:From July 2022 to February 2023, convenience sampling was used to select 220 patients who underwent PCI at Yantai Yuhuangding Hospital affiliated with Qingdao Medical College, Qingdao University as the study subject. A survey was conducted on patients using the General Information Questionnaires, Self-Efficacy for Exercise Scale, Illness Perception and Behavior Questionnaire in Patients with Coronary Heart Disease after PCI, Social Support Rating Scale, and Exercise Rehabilitation Compliance Follow-up Scale.Results:A total of 220 questionnaires were distributed, and 215 valid questionnaires were collected, with an effective response rate of 97.73% (215/220). The Exercise Rehabilitation Compliance Follow-up Scale in 215 patients after PCI was (11.35±3.85). The mediating effect of exercise self-efficacy between social support and exercise compliance was 0.150 [95% CI (0.055, 0.167), P<0.01], and the mediating effect of disease cognition between social support and exercise compliance after PCI was 0.065 [95% CI (0.016, 0.090), P<0.05]. The direct effect of social support on exercise compliance was 0.238 [95% CI (0.064, 0.278), P<0.01], and the indirect effect was 0.215 [95% CI (0.083, 0.233), P<0.05], and the mediating effect accounted for 47.46% of the total effect. Conclusions:Social support can directly or indirectly affect the compliance of patients with home-based exercise rehabilitation through the mediating effect of exercise self-efficacy and post PCI disease cognition. Medical and nursing staff can improve patient exercise self-efficacy and disease cognition by constructing intervention strategies based on social support, thereby enhancing home-based exercise rehabilitation compliance.

OBJECTIVE: To explore lung ultrasound radiomics features which related to extravascular lung water index (EVLWI), and to predict EVLWI in critically ill patients based on lung ultrasound radiomics combined with machine learning and validate its effectiveness. METHODS: A retrospective case-control study was conducted. The lung ultrasound videos and pulse indicated continuous cardiac output (PiCCO) monitoring results of critically ill patients admitted to the department of critical care medicine of the First Affiliated Hospital of Guangxi Medical University from November 2021 to October 2022 were collected, and randomly divided into training set and validation set at 8:2. The corresponding images from lung ultrasound videos were obtained to extract radiomics features. The EVLWI measured by PiCCO was regarded as the "gold standard", and the radiomics features of training set was filtered through statistical analysis and LASSO algorithm. Eight machine learning models were trained using filtered radiomics features including random forest (RF), extreme gradient boost (XGBoost), decision tree (DT), Naive Bayes (NB), multi-layer perceptron (MLP), K-nearest neighbor (KNN), support vector machine (SVM), and Logistic regression (LR). Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive performance of models on EVLWI in the validation set. RESULTS: A total of 151 samples from 30 patients were enrolled (including 906 lung ultrasound videos and 151 PiCCO monitoring results), 120 in the training set, and 31 in the validation set. There were no statistically significant differences in main baseline data including gender, age, body mass index (BMI), mean arterial pressure (MAP), central venous pressure (CVP), heart rate (HR), cardiac index (CI), cardiac function index (CFI), stroke volume index (SVI), global end diastolic volume index (GEDVI), systemic vascular resistance index (SVRI), pulmonary vascular permeability index (PVPI) and EVLWI. The overall EVLWI range in 151 PiCCO monitoring results was 3.7-25.6 mL/kg. Layered analysis showed that both datasets had EVLWI in the 7-15 mL/kg interval, and there was no statistically significant difference in EVLWI distribution. Two radiomics features were selected by using LASSO algorithm, namely grayscale non-uniformity (weight was -0.006 464) and complexity (weight was -0.167 583), and they were used for modeling. ROC curve analysis showed that the MLP model had better predictive performance. The area under the ROC curve (AUC) of the prediction validation set EVLWI was higher than that of RF, XGBoost, DT, KNN, LR, SVM, NB models (0.682 vs. 0.658, 0.657, 0.614, 0.608, 0.596, 0.557, 0.472). CONCLUSIONS The gray level non-uniformity and complexity of lung ultrasound were the most correlated radiomics features with EVLWI monitored by PiCCO. The MLP model based on gray level non-uniformity and complexity of lung ultrasound can be used for semi-quantitative prediction of EVLWI in critically ill patients.

The Cronbach's α coefficient of Chinese version of PedsQL TM 3.2-DM was 0.927 and that of 4 dimensions were respectively 0.885, 0.910, 0.828 and 0.798. After assessment by panel of experts, the content validity index of Chinese version of PedsQL TM 3.2-DM was 0.97 and the content validity index of every item was from 0.80 to 1.00. A total of 4 common factors were extracted by exploratory factor analysis and the cumulative variance contribution rate was 59.539%. In addition, the factor loading of each item on its common factor was over 0.4. Conclusions:The Chinese version of PedsQL TM 3.2-DM has good reliability and validity, which can be used as a simple tool for self-assessment of quality of life in children aged from 8 to 19 years with diabetes.

Objective: To evaluate the nursing workload in surgical departments by decision tree method. Methods: The indexes of nursing workload of 23 surgical departments were analyzed with decision tree method from February 20 to March 26 in 2017. Results: According to decision tree analysis, the number of admitted patients was high-priority variable (F=39.128, P=0.000), and the nursing workload was divided into four grades by number of admitted patients ≤ 1, 17, respectively. The suboptimal variables were number of operations (F=7.578, P=0.046) and number of electrocardiogram monitors used (F=28.306, P=0.000), the nursing workload was further divided into six grades by number of operations ≤ 5, number of operations>5 and number of electrocardiogram monitors use ≤ 5, number of electrocardiogram monitors use > 5, respectively. Conclusions The number of admitted patients, electrocardiogram monitors used and operative patients were significant indexes of nursing workload in surgical departments, which helps the nurse managers evaluate the nurse performance and optimize human resource allocation based on decision tree analysis and clinical practice.

bjective? To expLore the status quo of workLoad in primary nurses at different LeveLs and to provide a basis for hierarchicaL management over nursing staff. Methods? TotaLLy 45 wards of a Class Ⅲ Grade A hospitaL in Yantai City were seLected by cLuster sampLing from February 20th to March 19th, 2017, incLuding 23 from internaL medicine departments and 22 from surgery departments. Nursing workers were divided into 5 LeveLs ranging from N0 to N4 according to hierarchicaL management protocoLs. The seLf-designed workLoad questionnaire was used to investigate All primary nurses at different LeveLs in terms of patients in charge, direct and indirect nursing items and waLking distance during work. The workLoad of totaLLy 7 113 nurses at different LeveLs was investigated. ResuLts? There was statisticaL difference in the number of patients in charge, criticaL patients, high-risk patients with pressure uLcers, high-risk patients with pressure faLLs and severeLy dependent patients between nurses at different LeveLs (P＜0.05). The top 3 time-consuming nursing items in primary nurses at different LeveLs were identicaL, which were drug therapy, severity assessment and observation and heaLth education. Primary nurses at N0 and N1 LeveLs needed more time for therapy-reLated preparation than primary nurses at N2 and N3 LeveLs (P＜0.05). There was statisticaL difference in number of steps per shift during work between nurses at different LeveLs (P＜0.01). ConcLusions? The number of patients in charge and the patients' severity correspond to the LeveLs of primary nurses. The nursing work of these primary nurses at different LeveLs are basicaLLy the same except for cLinicaL teaching items. Nursing managers shaLL expLore a hierarchicaL management modeL over nurses, properLy configuring nurses at different LeveLs, giving fuLL pLay to the force of the nursing team, and managing the nursing team scientificaLLy according to cLinicaL practice in China.
